SPRINGJIATTRESS STRUCTURE.

Application filed November 12, 1927. Serial No. 282,729.

My invention relates to s ring mattress structure for beds, and one the objects 18 to provide a structure of this character wherein the spring action is evenly and um- 6 formly distributed throughout the entire mattress surface thereby providing maximum ease and comfort for the user Another object is to provide a highly efficient spring mattress structure which is [0 simple in construction and cheap to manufacture.

A further object is to provide a mattress structure including a plurality of springs which are so positioned and associated with N each other as to carry out the foregoing objects, at the same time being adapted. to

carry maximum loads, whether evenly 0r unevenly distributed, without permanent distortion.

Other objects and advantages will become apparent as this description progresses and by reference to the drawings. wherein,

Figure 1 is a top plan view of a portion of a spring mattress structure embodying my '6 invention. Since both ends and sides of the mattress structure and thespring members associated therewith are identical, only a portion of the entire mattress structure is shown.

Fig. 6 is a vertical section taken at line 6-6 on Fi re 5 and clearly showing the 5 manner of interengaging the springs of the upper and lower tiers,

Fig. 7 is an enlarged vertical section taken on line 77 of Fig. 4.

Referring particularly to the form shown in the drawings, I may emplo a rectangular-shaped fraine consisting 0 side bars 10 and end bars 11 formed, preferabl of angle iron and rigidly fastened toget er by a plurality of bolts or rivets as indicated at i 12. The side and end bars at both sides and right angles to present an edged supporting.

surface. The 'U-arms of these strips are extended horizontally and bolted or riveted to the horizontal flange of the side bars as indicated at 15.

The spring structure which I em 10y is supported by the frame and, pre erably, takes, in part, the form of a plurality of funnel-shaped sprin 16 having a lower cylindrical base portion 16 seated upon the horizontally-extending arms of the intermediate bars 13 withtheir lower coils interengaged therewith. These coils are further anchored to the bars 13 by a wire 17 laced upon the bars 13 and through the lower coils in an obvious manner (Fig. 3), the ends of such wires being hooked as at 18 to prevent disengagement from the springs 16 at the ends. The end bars 11 support a plurality of equally spaced coil springs 19 which have an upper funnel-shaped part 19 and a lower barrel-shaped part 19". The lower part of these springs is engaged with and anchored to the end bars by passing the lowermost coils through suitable openings in the vertical flange of that bar in' a manner well known. The springs 16 and 19 serve as border springs and, due to their shape, provide, in effect, a double spring action in conjunction with other and inner springs to be described later. The upper coils of these border springs are held in aligned position and securely interlocked with and by a border rod 20 by a wire 21, in a well known manner as shown in Fi 3.

Intermediate the borrfer sprin I employtwo tiers (upper and lower) 0 springs arranged in rows, the springs 22 of the lower tier being arranged in staggered relation to the springs 23 of the uper tier. All of these springs, including t e border springs, are equally spaced and 'arran ed so as to lie in uniformly spaced latera and lon tudinal rows extending throughout t 6 length and Width of the mattress structure.

to add strength, lessen t 1e possibility of dis The springs 22 of the lower tier or rows are funnel-shaped and the lower part of each coil is sup orted upon the adjacent upturnededge of t e intermediate bars 13 and are anchored thereto b wires 24 extending longitudinally of the rame and looped through the lower coils of such s rings and under their supporting bars 13 Figs. 4 and 7).

The springs 23 of the ili pper tier or row are also funnel-shaped. e lower springs are so spaced that the adjacent edges of their upper coils lie closely together and the lowermost coils of upper springs are interengaged or turned upon the adjacent upper coils of the lower springs, so that a portion of each adjacent upper coil lies within the coils of the upper springs 23 (Figs. 5 and 6). The lower springs thus support the upper sprin s and loads imposed upon the upper springs will be partially borne by the lower springs and, due to the staggered relation of these springs, the spring action is equally distributed along the upper surface. It is desirable that the upper and lower springs be positively secured together (Figs. 5 and 6) and held in predetermined lateral and longitudinal alignment, and to this end I emplo longitudinal wiresv 25 which are anchore to the end-border coils 19 and pass throu h the lower coils of the upper springs 23 and, preferably, beneath the portions of the adjoining upper coils of the lower springs 22 which are within the lower coils of such upper springs. Similar wires 25 are also carried by the side border springs 16 at the base of their funnel-shaped portion,

' such wires bein anchored to the end springs roout ig. 3,

of this group. he wires 25 and 25" are vided with depending humps throu their length, as shown h wire 25 in placement of the springs along the wires, and to aid generally in positively anchoring the coils together. It Will be noted that certain of these humps are so located and shaped (Figs. 3 and 6) that the extend downwardly within the coils of t e upper springs which further aids in holding the upper springs in place (Fig. 6). To completely and positively secure the springs 22 and 23 and 16 and 19 together as a spring unit, lateral Wires 26 are anchored to opposite side-border coils 16 atthe base of their funnel-shaped ortion and preferably, at right angles to t e longitudinal wires 25 and 25. These wires 26 extend along the upper portion of the lowercoils and pass through and within the lower coils. of the upper springs in such away as to loop over the enclosed section of the upper coils of the lower s rings, as shown in Fig. 6, thereby positive y securing the coils together and preventing lateral or longitudinal displacement of the same. The lower springs 22 adjacent the side-border coils are of lesser width at the top than the other coils of that group and their upper ortions adjacent the springs 16 are supported and confined b the respective lateral wire 26 which passes t ereover. These latter springs are thusly anchored to the side border coils so as to provide a staggered relation between such springs and so that loads imposed upon the border springs 16 will be partially imposed upon and borne by the adjacent lower springs 22. Wires 26 similar to wires 25 serve to additionally secure the end border springs 19 (Fig. 1).

he upper springs 23 are further supported and held in s aced relation at the top by a plurality of cy indrical coil springs 2 and28. These springs 27 and 28 are arranged at right angles to each other with their central coils turned or wound upon each other (Fig. 1) so that loads imposed upon one of such springs are artially borne by the other. Each spring 2 or 28 is provided with a hook at opposite ends which is connected to the uppermost coils of the diagonally opposing springs 23 so that all of the uppersprings 23 are connected together in a uniformly yieldable manner; and such upper springs are also connected to the side and end border springs 16 and 19 by the springs 27 and 28 (Fig. 1).

It is believed that the spring action is clear from the foregoing. Loads imposed upon the mattress surface will be borne in part by both the upper and lower springs 23 and 22 and by the border-springs 16 and 19. The staggered relation between the upper and lower springs and between the sideborder springs and lower springs with the spring connections between the upper springs and border springs presents a continuous spring surface throughout the mattress structure and the spring action is uniform and equally distributed throughout the mattress surface, all of which provides for maximum comfort for the user. Furthermore, according tomy invention the spring devices are so anchored and secured together that the above action is insured and they are held in a. predetermined alignment and the possibility of sagging and permanent distortion is eliminated without interfering with the desired spring action and uniform distribution of the same.
